Before you go any further...have you done a compression test?
How many miles are on the bike?
Once running does the bike run normal? Will it bum start easily? I'm not too familiar with the FSE models. Do they have a diagnostic feature on the ECU like the Husky TE's or TXC's?
Maybe a phone call to one of the boys from Gofasters is in order 320-839-7143
Good Luck
